In a large pot, over medium heat, sauté the onion and garlic in oil or butter until softened.
Place the pumpkin and potato pieces in the pot and cook, stirring frequently, for a few minutes.
Add the vegetable soup to the pumpkin and bring to a boil. Then reduce the heat and simmer gently until the pumpkin is completely tender and can be easily mashed with a fork (about 20-25 minutes).
For a smoother soup, use a blender to purée it until it becomes creamy and perfectly smooth.
Now pour in the cream and stir carefully, allowing the soup to simmer gently for another 5 minutes. Adjust the amount of salt to suit individual preferences.
Let's warm up with a delicious serving of pumpkin cream soup! Serve it hot, and for extra flavor and appearance, garnish with pumpkin seeds, ground paprika, or herbs. Enjoy!
